Safety instructions and measures 1 Safety instructions and measures Intended use The Types RV350D/R, RV370D/R, RV380D/R and RV390D/R Pneumatic Actuators are de- signed for operating a mounted globe valve. In combination with the valve, the actuators are used to shut off the flow of liquids, gases or vapors in the pipeline. Depending on the ver- sion, the actuators are suitable for throttling or on/off service.

Safety instructions and measures Explosion-protected versions of this device must be operated only by personnel who has un- dergone special training or instructions or who is authorized to work on explosion-protected devices in hazardous areas. Personal protective equipment RINGO recommends wearing the following personal protective equipment when handling the pneumatic actuator: −...
Safety instructions and measures Responsibilities of the operator Operators are responsible for proper use and compliance with the safety regulations. Opera- tors are obliged to provide these mounting and operating instructions as well as the refer- enced documents to the operating personnel and to instruct them in proper operation. Fur- thermore, operators must ensure that operating personnel or third parties are not exposed to any danger.
Safety instructions and measures 1.2 Notes on possible personal injury WARNING Crush hazard arising from moving parts. The actuator contains moving parts (actuator stem), which can injure hands or fingers if inserted into the actuator. Î Do not touch the actuator stem or insert hands or finger into the yoke or beneath the actuator stem while the air supply is connected to the actuator.
Safety instructions and measures WARNING Exposure to hazardous substances poses a serious risk to health. Certain lubricants and cleaning agents are classified as hazardous substances. These substances have a special label and a material safety data sheet (MSDS) issued by the manufacturer.
Page 10
Safety instructions and measures NOTICE Risk of actuator damage due to the use of unsuitable lubricants. The lubricants to be used depend on the actuator material. Unsuitable lubricants may corrode and damage surfaces. Î Only use lubricants approved by RINGO. EB 8318 EN...
Safety instructions and measures 1.4 Warnings on the device Warning symbols Meaning of the warning Location on the device Warning against the incorrect use of the lifting eyelet/eyebolt or swivel hoist on the actuator. Only attach load-bearing slings to them to vertically lift the actuator on its own (without the valve).
